Hi, folks, I'm following the instructions in the 1.7 user manual to set up Kerberos impersonation. I'm using Ambari 2.1.2.1 to specify the configuration in accumulo-site.xml.
If I understand the manual correctly, I need to define a property key of the form: instance.rpc.sasl.impersonation.username/server@REALM.users. The value should be a CSV list of kerberos principals. The problem is that Ambari will reject a property key with the characters "@" or "/". Is Ambari being overly restrictive or have I misunderstood the user manual? Is there any workaround other than manually editing accumulo-site.xml (which I think will be overwritten as soon as Ambari discovers that it's out-of-sync)? Thanks, -Russ
